Summary
A 16.3-inch center display anchors the redesigned 2027 Sierra cabin, with the Denali Ultimate adding an articulating screen, a 12.2-inch gauge cluster and an optional 11.5-inch passenger display.
Denali Ultimate and AT4X also get a 16-speaker Bose system with headrest speakers — a pickup-truck first — plus a reworked MultiPro center console with storage, a work surface and available dual MagSafe chargers.
Under the hood, GMC carries over the TurboMax four-cylinder and 3.0-liter Duramax diesel while adding new 5.7-liter and 6.6-liter small-block V8s; every trim now uses a 10-speed automatic.
AT4 and AT4X receive bigger off-road hardware, including 34-inch and 35-inch tires respectively, while the AT4X adds Multimatic Jounce Control Dampers alongside DSSV units.
Pricing and V8 output figures are still undisclosed, but GMC plans to launch the 2027 Sierra later this year as it pushes the model further upmarket from its Chevrolet Silverado sibling.
